Right now, to the "Gma" get out and give. It is an initiative inspired by Disney's summer of service. It is the littlest things that make the biggest difference. I am highlighting robin hood and the lemonade program, raises money for those less fortunate, but teaches kids how rewarding it is to give back. What do you get when you take the time-honored tradition of the neighborhood lemonade stand, sprinkle in a few friends. Thank Y Thank you. Reporter: And perhaps the money be will go to charity? You get to teach kids about the important lesson of giving back. The robin hood foundation's lemonade program does just that. No matter what age you are you can always make a difference. Reporter: Cup by cup, the program's mission is to raise money to help the nearly 2 million new yorkers living in poverty. Never too young to start thinking about how to help others. And thinking about ifphilanthropy growing up. Reporter: And offering free lemonade on a hot summer day in return for a donation of any size. And boy did customers come through. They raised $380, which goes a long way when you consider that a robin hood foundation can feed a family for a week with $75, and $100 gives a family a place to stay for the night. It gives you a good feeling. $1.20 is enough for a meal in New York City. Just that makes a difference. Reporter: It's a refreshing way to make a difference and teach kids how to give back, one sip at a time. So here's our stand, and you never charge. You always give the lemonade, and you just ask for a donation. Whatever you can do. You are the spokesperson for robin hood, why such a hit? So simple and easy, and kids love it. It's exactly what you said. So simple and easy. Robin hood's mission is to fight poverty in New York City. It's a way for kids to get involved. We have been doing this for ten years, and we have raised over a million dollars to help poor people in New York. It's a way for young people to get involved and make a difference. I want to talk to co-founders. First we have Noah. Talk to me about this initiative. Just the idea of a lemonade stand and how you don't want kids to charge, and how generous people have become as a result. And people in my community, they were throwing in $20 bills because they love the idea. It's amazing. Ten years ago we started -- we did a little lemonade stand outside of the house, and instead of using the proceeds, we decided to give it to the robin hood foundation. We decided that was the best idea. It sprang into something more and became bigger. Let many ask you, what's your idea of how this has grown and how much you have raised this summer? It's amazing. We have raised $105,000 so far, and we to want raise $150,000. This is the other brother, what do you want to say to everybody? Happy with what we have done with lemonade and look forward to continued success. Donate. Lemonade for our lemonade stand, thank you so much for donating that. We're going to hand out lemonade right now. For more information go to good morning america.com on Yahoo!. You can get involved, you can give. So please do.
